Divinity 2 Nude Patch
Here is a pleasant Divinity 2 nude skin that works in my copy of DKS as well. Appears to only work on the player character (which has to be female obviously), and only visible when you take her armor and clothes off. Feel free to run about town naked as the day you were born, but don't expect much protection out in the wild.
After you add the files to your game directory, you'll start the game with a different shortcut. Specific instructions in the zip.
